a. What is the longest English word that begins and ends with the same letter?

b. What letters do not provide even one qualifying candidate having this feature?

c. Same as a, but no repeated letters except the first and the last (none of the title's word qualify).

(In reply to computer solutions by Charlie)

In your a) part several entries appear twice - any reason for it?
